Detectives investigating the murder of a man who was gunned down in a pub have arrested four people.
The victim, named by sources as 23-year-old Mark Short, was shot in the Cotton Tree pub in Market Street, Droylsden, Greater Manchester, shortly before 11.50pm on Friday.
It is understood he was celebrating with family at a 60th birthday party and was shot by a lone gunman.
Greater Manchester Police said a 34-year-old man has been arrested on suspicion of murder.
A 52-year-old woman has been arrested on suspicion of conspiracy to commit murder and possessing class A drugs and two other men, aged 21 and 18, have been arrested on suspicion of assisting an offender.
Detective Chief Inspector Denise Worth, of the Major Incident Team, said: "Mark was a young man who was tragically shot dead while in a pub with family and friends and our thoughts are with his loved ones who have, understandably, been left devastated.
"We remain in the very early stages of our investigation and I continue to appeal to anyone with information about the gunman, his accomplices or conspirators to contact us in absolute confidence.
"There continue to be extra police officers in the area so if anyone wants to provide information about this or has any concerns please come and talk to us."
A Home Office post mortem concluded Mark Short died from a gunshot wound to the neck.
Two men, aged 25 and 26, were shot in the leg and a 29-year-old man was shot in his lower back.
The men, who are believed to be related to Mr Short, are being treated in hospital. Their injuries are not thought to be life threatening.
Speaking from the scene yesterday, Chief Superintendent Nick Adderley said a man burst into the private party and opened fire.
"We don't believe this to be a random attack, although we are not clear about who the intended victim was," he said.
"We understand this was a family occasion and that a lone gunman walked into the premises and opened fire on a group of males stood by the pool table."
Around 20 people, aged 18-65, were said to be in the pub at the time.
Mr Adderley said officers were keeping an open mind about the motive but said all the victims were known to the police.
The gunman was wearing a balaclava and escaped in a Ford Focus which was found abandoned and alight in Ellison Close, Hattersley, a short time later.
Police believe the gunman used a revolver and that four shots were fired in the pub.
It is understood that two people may have been waiting outside the pub in the getaway car.
The shooting is not thought to be gang-related, but Mr Adderley said that could not be ruled out by investigators.
He said the victim's family were "deeply shocked" and were being looked after by police family liaison officers.
Floral tributes were left at the scene.
